What are Dual Sensor Smoke Alarms?
Dual sensor smoke alarms are smoke alarms which use two different detection methods for identifying fires. Many fire safety organizations recommend the installation of dual sensor smoke alarms because they cover a broad range of fires, making them much safer than single sensor alarms. As with any smoke or fire alarm, you should check your smoke detectors and replace their batteries at least twice a year. Many people like to do this when the time changes, as this biannual event already requires people to change their clocks and adjust other timed household devices. The innards of a dual sensor smoke alarm include a photoelectric sensor and an ionization sensor. Photoelectric sensors are very good at detecting slow, smoldering fires like fires which start in mattresses, couches, carpeting, and drapes. An ionization sensor can detect a sudden burst of flame like a grease fire. The combined sensors work together to alert people to smoky conditions and fires. The photoelectric smoke alarms
